How to store hive query result in json format in a file?

Asked 2020-Apr-09 at 22:07

I want to store the hive query result to a file in JSON format. Through Brickhouse jar I can get the query output in JSON format but am unable to store that in a file or table. The query I'm trying is given below. When the INSERT OVERWRITE query runs, it gives an error; how can I solve this error? Is there a way to store query results in JSON format through queries?

QUESTION

Select result of two Hive tables as JSON output

Asked 2019-Feb-02 at 04:13

I have a requirement where I need to join multiple Hive tables which are in ORC format and present the output as JSON.

For example if I have two Hive tables with 1 to many relationship, I want the output to be JSON with embedded relationship and array.

Is there native Hive UDF we can use to achieve this ?

I tried googling stuff like to_JSON from https://github.com/klout/brickhouse but looking for something more Hadoop native and not third party.

Can anyone help me with this.

Create Hive table using JsonSerDe.

Then insert into json table by selecting the result of join.

QUESTION

jQuery remove or add style to last of specific type of element

Asked 2018-Nov-07 at 17:52

I have a jQuery page that has a few things going on. All of the functionalities are complete. The only thing that's not complete is removing the last hr (only the last one) of each table. I need to know how to the last of a specific type of element in an array. All the elements that are wrapped in the tables are their own array. I need to loop through each of those tables and only remove the last hr in the table for each table. I've tried many methods and can't seem to get it. The code I have below only removes the last hr for the last table. This doesn't complete my task.

jQuery/ JavaScript Code (Everything works except for removing the last HR)

If you're trying to remove the last HR on each table you don't need the for loop, try this.

QUESTION

Does .beeline serve the same purpose as the .hiverc?

Asked 2017-Dec-08 at 13:44

My office is currently transitioning from hive to beeline.

I currently have a .hiverc file that loads some JAR files for me and I would like to transition everything in the .hiverc to beeline if possible.

Currently the only file in my directory that seems relevant is the .beeline (unless I am looking for .beelinerc, haha). Does beeline support what hive supported with the .hiverc file?

.hiverc contents:

ANSWER

Answered 2017-Jun-21 at 14:45

According to this Jira Ticket , your .hiverc will work with beeline as it works with hive-cli if your Hive Version is > 0.14.0.

I don't know what your data looks like in Hive because you didn't provide that information so here is how I loaded your XML into Hive.
